Brent Pautler to Present on PFASsive at Eurofins Webinar

Brent Pautler, PhD and his co-presenter Andrew Patteron, Eurofins, will present in the “PFASsive: A Diffusion-Based Passive Sampler” Eurofins webinar at 1:30 pm (ET) on May 9, 2023.  

 Brent received his Ph.D. in environmental analytical chemistry in 2013 where he gained advanced technical experience in spectroscopy, chromatography, mass spectrometry, passive sampling, and chemistry informatics. Throughout his career, he has worked with scientists, engineers, and consultants, applying his chemistry and information technology expertise to help them solve unique problems in the laboratory and the field. His role includes managing and advancing SiREM’s passive sampling portfolio, analytical testing services while supporting Compound Specific Isotope Analysis (CSIA) business development. 

 Eurofins BioPharma Product Testing is the largest network of harmonized bio/pharmaceutical GMP product testing laboratories worldwide providing comprehensive laboratory services for the world’s largest pharmaceutical, biopharmaceutical and medical device companies. Their service offerings are fully comprehensive and include testing of drug substance, final product, intermediates, and starting materials for both small and large molecule drug products. 

 Eurofins Environment Testing training courses provide unique and valuable opportunity to learn from an industry-leading laboratory with decades of experience in analysis and investigations. 

 Their Goal: To educate professionals and raise the standard of excellence throughout the environmental industry. 

 Continuing Education: Eurofins offers Professional Development Hours (PDH) for attendance to our webinars. 


 Per-and Polyfluoroalkyl Substances (PFAS) have emerged as a concern at many sites as they are persistent, bioaccumulative, and have demonstrated toxicity in laboratory animals, therefore it is a critical need to understand their migration pathways and bioavailability for proper delineation and risk characterization. Although there are established grab sampling techniques available for PFAS, these capture the total concentration which may result in an overestimation of risk to human and ecological receptors. Passive sampling in sediment porewater and surface water is an accepted approach to assess bioavailability and risk through the dissolved phase of many known contaminants (i.e., PCBs, PAHs, pesticides, metals etc.). Given their partially water-soluble nature, a diffusion-based passive sampler is a good candidate for quantification of dissolved PFAS. This presentation will highlight both targeted and non-targeted results from in situ field testing of a novel passive sampler, PFASsive, and compare these results with those obtained from traditional grab sampling.
